Latest TAC Protocol (TAC) News Update

Deep Dive

1. Major SDK Overhaul & New Modules (September 2025)

Overview: This major version jump (v0.7.0) significantly expanded the SDK's capabilities, making it easier for developers to build applications that move assets between TON and TAC. It adds tools for handling different asset types and simulating transactions before they are sent.

The update introduced a comprehensive Assets Module for working with fungible tokens (FT), NFTs, and TON assets. A new Simulator Component allows developers to estimate gas and fees for transactions internally, reducing failed transactions and costs. Performance was boosted by parallelizing blockchain queries during SDK startup. The update also refined core architecture, including transaction managers and sender utilities, for greater stability.

What this means: This is bullish for $TAC because it directly empowers developers to build more complex and reliable applications on the protocol. Faster initialization, better error handling, and pre-transaction simulations lead to a smoother and more secure experience for end-users, which can drive adoption. (Source)

2. Cross-Chain Transaction & Fee Enhancements (June 2025)

Overview: Version 0.6.3 and 0.6.4 focused on improving the core function of bridging assets between chains. They made it possible to send multiple cross-chain transactions at once and improved the system's resilience.

Key additions include the sendCrossChainTransactions method for batch operations, which is more efficient than sending individually. The SDK also enhanced error handling specifically for these transactions to provide clearer feedback if something goes wrong. The default infrastructure was switched to use a more reliable set of service endpoints.

What this means: This is neutral to bullish for $TAC as it improves the fundamental utility of the protocol. Batch transactions can lower costs and save time for users and developers, while better error handling increases the network's overall reliability and trustworthiness. (Source)

3. Sequencer Upgrades & Fee Calculations (May 2025)

Overview: These updates (v0.6.1 and v0.6.2) fine-tuned the economic and operational layers of the SDK, particularly how transactions are processed and paid for.

The integration with a v3 sequencer and the new LiteSequencerClient improved the backend infrastructure for handling transaction requests. Crucially, it added the getTVMExecutorFeeInfo method, allowing for precise calculation of execution fees on the TON Virtual Machine (TVM) before a user commits to a transaction. This brings more cost predictability.

What this means: This is bullish for $TAC because predictable fees and upgraded backend infrastructure reduce friction for users. Knowing the exact cost upfront prevents surprises and makes the protocol more user-friendly, which is essential for attracting a mainstream Telegram audience. (Source)

Conclusion

TAC Protocol's development trajectory, as of the last documented updates, shows a clear focus on maturing its core infrastructure—enhancing developer tools, cross-chain efficiency, and user cost certainty. While these foundational improvements from 2025 are positive, how has the development pace evolved to support the protocol's recent market activity and integrations?

1. Cosmos Labs Admits Misjudging Critical Bug (29 August 2026)

Overview: Cosmos Labs published a technical report admitting it misjudged an integer underflow vulnerability in the shared Cosmos EVM software. This flaw was exploited between August 20 and 25, 2026, across six blockchain networks, leading to the theft of approximately $5.7 million in tokens. TAC Protocol was a major victim, losing nearly 3 billion TAC tokens (about 62% of its supply at the time) from a single account, forcing the chain to halt. The bug was first reported via a bounty program on April 25 but was not properly flagged as critical, leading to a delayed and insufficient patch on August 19, just hours before the first attack.

What this means: This is bearish for TAC because it represents a catastrophic failure in shared infrastructure security, directly draining a majority of the token's circulating supply and halting network operations. It severely damages trust in the chain's stability and the broader Cosmos EVM ecosystem. The incident highlights critical dependencies and coordination failures that could hinder TAC's recovery and future adoption. (TradingView)

2. Binance Futures Applies Price Protection (27 August 2026)

Overview: Binance Futures announced it would apply the Last Price Protected (LPP) Mechanism to the TACUSDT Perpetual Contract starting August 27, 2026. This move was triggered by observed spot price divergence across multiple exchanges. The mechanism temporarily changes the mark price calculation to a 10-second average with a ±1% cap per second and reduces the capped funding rate to ±0.005% to prevent extreme volatility and liquidations during the transition period.

What this means: This is a neutral-to-bearish market structure update. It indicates that TAC's spot markets experienced significant instability and fragmentation, likely exacerbated by the recent hack and sell-off. While the mechanism protects traders from wild swings and potential manipulation on the derivatives side, its necessity underscores the token's current illiquidity and heightened risk profile.

Conclusion

TAC Protocol's trajectory is currently defined by crisis management following a devastating security exploit and subsequent exchange interventions to curb volatility. The key question now is whether the team can execute a secure recovery and rebuild user confidence after such a significant breach.
